Do Black Dog LED grow lights work with 220V / 240V?

Yes, our lights will work with 110/120 volts and 220/240 volts; PhytoMAX-2 even work up to 277 volts-- all you need is the right power cord to plug into the outlet. Our lights come with a heavy-duty 14 gauge 8-foot North American 120V cord, but we have other lengths available for both voltages here on our website.
